"Every day, I'm so thankful to have this amazing man as my partner," the actress wrote on Facebook last year. "I would not be where I am in this life if I didn't have his constant encouragement and complete support. He changes diapers, makes carpool runs and always has time to give me a much needed pep talk...(He makes a really good latte too!)"

Witherspoon credits Toth with helping to inspire her to take the next step in her Hollywood career: Producing.

"He said, 'You should produce movies. You read more books than anybody I know. You should just buy some of them and turn them into films,'" Witherspoon quoted Toth as saying, in an interview with Harper's Bazaar posted in January.

The actress' production company, Pacific Standard, helped make her 2014 film Wild, which earned her an Oscar nomination, Gone Girl, which garnered Rosamund Pike a nod, and the comedy Hot Pursuit, which featured Witherspoon and Sofia Vergara. Witherspoon is also co-producing her new HBO comedy series Big Little Lies, which also stars Nicole Kidman, Alexander Skarsgård and her Wild co-star Laura Dern and is set to premiere in 2017.

Witherspoon's former company, Type A Films, co-produced the big-screen and straight-to-video sequels to her hit film Legally Blonde.
